'eprosima::fastcdr::exception::NotEnoughMemoryException' what(): Not enough memory in the buffer stream error

Personne n'a encore pris cette issue.

Hello?

Ubuntu version : 22.04
ROS2 version : Humble

When running micro-ros-agent, the following error occurs:

terminate called after throwing an instance of 'eprosima::fastcdr::exception::NotEnoughMemoryException' what(): Not enough memory in the buffer stream

Let me explain some situations when that error occurs.

1. When running micro-ROS-agent on a Linux PC with Ubuntu22.04, ROS2 Humble installed, this device and another device are connected to the same network as a Linux PC with Ubuntu24.04, ROS Jazzy installed.

2. When running micro-ROS-agent on a Linux PC with Ubuntu22.04, ROS2 Humble installed, when connecting to the same network as this device and another device with a Linux PC with Ubuntu24.04, ROS Jazzy installed and running ROS2 Node via SSH.

3. When running micro-ROS-agent on a Linux PC with Ubuntu22.04, ROS2 Humble installed, when connecting to the same network as this device and another device with a Linux PC with Ubuntu24.04, ROS Jazzy installed, and entering ROS2 commands such as the ros2 topic list command and the ros2 topic echo /topic1 command via SSH.

This situation has occurred quite frequently, and my question is as follows:

1. Do you know how to fix the following error?

terminate called after throwing an instance of 'eprosima::fastcdr::exception::NotEnoughMemoryException' what(): Not enough memory in the buffer stream

2. Can that error occur simply because devices with different ROS2 versions (Humble, Jazzy) are connected to the same network?

3. When devices with different ROS2 versions (Humble, Jazzy) are connected to the same network, can an error occur simply by entering the command to connect via SSH?

4. When devices with different ROS2 versions (Humble, Jazzy) are connected to the same network, can the error occur when entering ROS2 commands or running ROS2 nodes?

If you know any of the questions I'm asking above, please help me.

Thank you.

Commencez par reproduire l’échec de micro-ROS-agent dans les scénarios réseau décrits Ubuntu 22.04/ROS 2 Humble et Ubuntu 24.04/ROS 2 Jazzy, y compris les cas de commandes SSH et ROS 2. Déterminez si des versions mixtes de ROS 2 déclenchent l’exception Fast CDR, puis documentez la cause racine, les exigences de compatibilité et une résolution vérifiée.
